Description

[Detailed description of the invention] [Industrial application field] The present invention is an improvement of fence-like structures, specifically, fence-like structures such as outer fences for enclosing sites, indoor/outdoor handrails, etc. The present invention relates to a practical fence-like structure whose structure is improved to be easier to assemble and more stable.

[Conventional technology and technical issues to be solved]

As is well known, fence-like structures such as outer fences and handrails are widely used in the fields of architecture and civil engineering.

By the way, careful consideration is given to the structural strength of handrails and outer fences placed on the rooftops of buildings, as safety is required in addition to design. It was natural that structures with unstable structures that could easily become loose were to be avoided. By the way, taking a handrail installed on the roof of a building as an example, as shown in FIG. 2, between the top rail piece 1 and the bottom rail piece 1, there are a number of blaster pieces 2, 2... ... is normally connected, but in the past, all of these blaster beams 2 were fixed with screws. Therefore, as assembly work is extremely time-consuming, assembly is rarely done at the construction site, and the method used is to take pre-assembled frame products at a factory and bring them to the construction site for installation. I was worried. However, the method of transporting and installing such frame-shaped products on the roof of a building has been criticized by various quarters, saying that the products themselves are bulky and inconvenient to transport and store. There were high demands for improvements.

This invention aims to improve the above-mentioned inconveniences of conventional fence-like structures, and allows for easy and quick assembly work at the construction site, and the strength of the connecting parts is stable in the assembled state. Therefore, it is a technical problem to provide a fence-like structure with a simple structure and high safety that does not rattle or move.

[Means adopted to solve the problem]

The means adopted by the present inventor to solve the above technical problem will be explained with reference to the attached drawings.
It is as follows.

That is, the present invention includes channel-shaped top rails 1a and 1b installed horizontally at the top of a fence-like structure, and a bottom rail 1 installed horizontally at the bottom of the fence-like structure.
, main pillars 3, 3, etc. that support these top rails 1a, 1b and bottom rail 1 at predetermined intervals and horizontally suspend them; The top rail 1a, 1b and the bottom rail 1 are composed of joined insert crosspieces 2, 2...
Insert crosspieces 2, 2...
The notch elastic pieces 21, 21 are cut into the top rails 1a, 21, and the notch elastic pieces 21, 21 open outward due to the biasing elasticity.
The top rails 1a, 1 are engaged with the insertion opening edge 11 of the insert slot 1b and the seat 14 of the bottom rail 1, while the upper ends of these insert bars 2, 2... abut against each other.
The gist lies in that ribs 12, 13 are provided protrudingly on the inner surface of the channel b to complete a fence-like structure that can prevent the insert crosspieces 2, 2, . . . from moving.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on embodiments shown in the accompanying drawings. Note that FIG. 1 is an explanatory elevational cross-sectional view of the fence-like structure (handrail) of this embodiment.

The handrail of this embodiment consists of top rails 1a, 1b and a bottom rail 1 that are vertically supported and horizontally supported in parallel by main pillars 3, 3, etc. erected on the ground, and a lattice between these top rails and bottom rails. It is composed of insert pieces 2, 2, etc., which are inserted and spliced in a shape.

In the handrail of this embodiment, the top rail 1
A and 1b are formed by combining a substrate 1a and a cap rail 1b having a cap-shaped cross section and fitted onto the substrate 1a, and both are pultruded aluminum products. Further, as the lower bottom rail 1, a channel-shaped aluminum pultrusion molded product with an open lower surface is used.

The insert crosspiece 2 in this embodiment is a hollow thin aluminum square bar, whose upper end passes through the insertion opening edges 11 provided at predetermined intervals on the base plate 1a of the top rail, and inserts the top rail into the top rail. Abutting against the bottom surface of the channel, the cap rail 1b
Each insert piece 2, 2...
prevents the head from moving sideways.

Furthermore, notched elastic pieces 21, 21 are formed in the upper and lower side surfaces of the insert piece 2, respectively, and the notched elastic pieces 21, 21 on the upper part of the insert piece 2 are connected to the top rails 1a, 1.
When the elastic piece 21 is inserted into the insertion opening rim 11 of b, the elastic piece 21 opens outward and engages the opening rim 11 in a retaining state, and the notched elastic pieces 21, 21 at the lower part of the insert crosspiece 2 , which is opened outward and engaged with the edge of a catch seat 14 recessed at a predetermined interval on the upper surface of the bottom rail 1 in a manner to prevent it from coming off.

In addition, in the same figure, 15 is an engaging part provided at the lower end of the cap rail 1b, and 16 is a hook part provided at the lower end of the same cap rail 1b.
This configuration is for engaging the engaging portion 15 with the side edge of the substrate 1a and elastically latching the hook 16 on the opposite edge of the substrate 1a.

[Effects of this invention]

As explained above, in the present invention, notched elastic pieces are cut into the insert crosspieces arranged in a grid pattern in the fence-like structure, and ribs are also formed on the inner surface of the channel of the top rail. By forming the notched elastic piece, it can be connected to the top rail and the bottom rail in a non-removal state by skillfully utilizing the biasing elasticity of the notched elastic piece, and the upper part of the insert crosspiece, which tends to move loosely, can be attached to the inner surface of the channel of the top rail. This can be effectively prevented by the formed ribs. Therefore, the fence-like structure of the present invention is structurally very strong and can be said to be a truly stable product without any problems such as rattling.

Furthermore, the fence-like structure of the present invention requires extremely little screwing, riveting, and other work during assembly, making it extremely easy and quick to assemble on-site, reducing construction costs. This can greatly contribute to savings and shortening the construction period.
